I'm done tracking FTS. CS Perfect World stats pretty much confirmed the .0033 chance for cases so there it is.. Unusualfiers - they seem like a 2.5% chance.... Crates, well they were a .0066 chance. and it was all that chance.. no weight for store purchases, hours, weekends, weekdays. i unboxed all at every time regardless of which.. only thing i am keeping an eye on now is if there is a weight percentage (similar to DOTA) added at the time they updated the HW effects..
